After taking a shower.
Kaede emerged from the bathroom with the warm steam. Her short-sleeved sleep shirt was stretched, outlining two rounded curves with small blemishes. The shorts ended at her upper thigh, revealing large areas of skin that were flush with an attractive pink from the steam.
Wiping her hair with a dry towel, Kaede walked towards Suzu's room.
She knocked, and without waiting for Suzu's reply, she opened the door.
"I'm done. Your turn."
Suzu's room was similar to Kaede's—very plain, without the cute decorations many girls liked.
Suzu was sitting on her chair, playing with her phone.
"Mhm."
Suzu subtly exited the app on her phone and nodded. She opened her closet to pull out fresh underwear and a nightgown.
Kaede casually looked at Suzu's sheer white thighs... just moments ago, she had been wearing black pantyhose! Now, she was bare-legged.
Plus, the System had just announced that 'Legs' were unlocked...
The pantyhose must have been soiled when Suzu used her legs to have intimate contact with him.
Suzu glanced at her sister thoughtfully.
She picked up her phone, subtly swiped the screen with her finger, and then placed it on a stand on the desk before heading to the bathroom to shower.
After Suzu left, Kaede's eyes darted around... Where did they do the bad thing?
Well... since they had gone this far, she might as well encourage it.
[System, designate Suzu as the 'Yellow Hair' (Home Wrecker).]
Kaede had only been bonded with the System for about a week and was still exploring its functions.
There was only one protagonist slot. After Rin was bonded and the direction was set to Reverse-NTR, the slots for protagonist and heroine were locked. The System said she had to experience it personally to draw the best manga.
Kaede, naturally, became the heroine.
Protagonist, Heroine, Yellow Hair... the first two were taken, leaving only the 'Yellow Hair' role.
The 'Yellow Hair' role didn't need to be bonded; Kaede could assign it freely.
[Confirmed. Does the host confirm designating Suzu Hoshizuki as the Yellow Hair? Corresponding functions will be unlocked upon confirmation.]
Kaede pouted... As if not designating her would make her NOT the Yellow Hair? Suzu had been secretly intimate with Rin, and her progress was even faster than mine! If not for the System, I wouldn't have known their relationship progressed so fast!
[Confirm!]
[Suzu Hoshizuki Status Panel Unlocked, Yellow Hair Exclusive Quests Unlocked, Yellow Hair Exclusive Shop Unlocked, Camera System Unlocked.]
[Open Suzu Hoshizuki Status Panel.]
Kaede quickly scanned Suzu's panel... Well, I'll be damned.
From basic attributes to body measurements, although the difference was small, Suzu was slightly ahead of Kaede in almost every category... What kind of victim heroine panel is this?
The home wrecker is bigger than me, seriously!?
But Kaede didn't really care about the panel. Even without it, she could feel it... she had always been the one being teased growing up. Her only victory was Rin choosing to date her.
[Open Yellow Hair Exclusive Shop.]
Kaede quickly scanned the listings and noticed many strange items.
For example, the 'Sperm Blocker' item could reduce Suzu's chance of getting pregnant... So, to prevent Suzu from getting pregnant while cheating, I have to complete quests to buy her contraceptives?
Was this to give her a sense of participation?
What kind of Supreme Cuckoldry is this?!
But... she had to buy it. At least until they graduated from university.
She could also use the Nurturing Points gained from exclusive quests to enhance Suzu, but the enhancement method was slightly different from Rin's.
She could use points to increase or decrease Suzu's bust, waist, and hip measurements, or make her skin softer, and she could even increase her sensitivity!
The System broke down the body into many fine parts: earlobes, tongue, throat, left breast, right breast, soles of feet, insteps... she could increase the sensitivity of these parts individually.
It cost 10 Nurturing Points for a 1% increase in sensitivity for one area. Unlike measurements, which could be increased or decreased, sensitivity could only be increased.
Although Kaede was tempted to try, she had just unlocked the Yellow Hair exclusive quests and didn't have any points for Suzu yet.
Besides the Yellow Hair exclusive quests and shop, Kaede noticed another unlocked feature.
[System, what is the Camera System?]
Kaede didn't know much about the Nurturing System. Quests and Shops were 'exclusive' to the Yellow Hair, Rin, and herself. But the Camera System had no such prefix.
[When Rin Ito engages in intimate contact with a Yellow Hair, the host can watch via the Camera System. Nurturing Points will be awarded based on viewing duration.]
[...]
The Yellow Hair steals my boyfriend, and I have to watch it?
Is this adding insult to injury?!
Kaede was too tired to complain.
[Open Yellow Hair Exclusive Quest List.]
Kaede felt weary... she needed to check the quests. She needed to complete quests and earn points to buy items from the Exclusive Shop.
[Quest 1: Where is the Magical Pantyhose?]
[Content: Find the black pantyhose Suzu recently took off.]
[Reward: 100 Nurturing Points.]
That's easy!
Suzu's room wasn't big, and there weren't many things in it. Finding a pair of pantyhose would be simple. Besides... she couldn't have put the soiled pantyhose back in the closet, and Kaede had been watching her—she hadn't had a chance to wash them in the shower.
Kaede simply bent down and saw a sticky black pair of pantyhose lying quietly under the bed. The scent of her boyfriend and her sister had completely blended together.
This is too easy.
The moment Kaede held Suzu's black pantyhose, 100 Nurturing Points were credited to her account.
[Quest 2: Sister's Disgrace]
[Content: Put on the black pantyhose found in Quest 1. Complete an 'erotic release' before Suzu returns, and return the black pantyhose to its original position.]
[Reward: 200 Nurturing Points.]
???
Putting them on was one thing; the sisters often shared clothes like pantyhose or stockings.
But... they only shared clean pantyhose.
These pantyhose were dirty and sticky with Rin and Suzu's mess. Not only that, but the quest required her to wear them to get off?
There was no time to hesitate. Looking at the soiled black pantyhose, Kaede gritted her teeth and pulled them on. She had to do this to earn enough Nurturing Points to buy Suzu the Sperm Blocker...
Without Suzu's body heat, the instant the wet pantyhose went on, a chill made Kaede tremble as if electrocuted. The undried pantyhose clung perfectly to her skin.
In her sister's room, wearing pantyhose soiled by her sister and her own boyfriend.
The misplaced sense of forbidden arousal made Kaede's body burn.
Only focused on completing the quest quickly, Kaede failed to notice Suzu's phone resting on the desk.
